HiQ® Hydrogen Carrier Gas Generator.
Background
In gas chromatography (GC), hydrogen offers important advantages over helium and nitrogen in terms of
speed analysis, sensitivity and resolution. However, laboratory location and safety concerns sometime
conflict with the storage and use of high pressure hydrogen cylinders. HiQ® hydrogen laboratory gas
generators are the economical alternative. Offering gas purity up to 99.9999%, silent operation, and supply
pressure up to 10.5 barg (155 psig). HiQ® hydrogen generators have been designed to meet the highest
quality and reliability standards.
Description
HiQ® Hydrogen Carrier generators employ the latest in Polymer Electrolyte Membrane (PEM) technology and
exclusive no maintenance PSA auto-drying technology and cascading capability for on-site production of
gaseous high purity hydrogen up to 99.9999%. No caustic solution is needed, and the small contained volume
(<40 ml) makes the HiQ® Hydrogen Carrier generator safe for operation in any laboratory. An auto shut-off
procedure places the unit in standby in the event of an internal error, and selectable alarms allow you to be
notified whenever operating conditions vary from the set point. The log file can easily be downloaded to a PC
via the USB interface to make the traceability and diagnostics more efficient.
With a small footprint of 16 x 35 cm the HiQ® Hydrogen Carrier generator saves space. It is compatible to all
major voltages and power supplies.

Applications
The internal pump forces distilled water to flow from the external water reservoir to the PEM electrolysis cell;
mixed with oxygen, a by-product of electrolysis, the water returns to the reservoir. On the way to the cell,
the water is filtered, then deionised through a special cartridge and its conductivity measured. The humid
hydrogen then passes through the membrane and is dried by a gas liquid separator and then by a static dryer.
Dry hydrogen is then passed through a high performance purification module based on a PSA principle, where
the final pressure is regulated by a proportional valve.
With its small size, trouble free operational and low maintenance environment, the HiQ® Hydrogen Carrier
generator is the ideal source of hydrogen as a fuel gas for flame tools, carrier gas application such as GC
and GC-MS (Mass Spectrometry), or as a source of pure hydrogen in plasma chambers and other isolated
environments.
